I am standing up a new installation of Nagios Core 4.4.5 on a RHEL 7 server to monitor all our RHEL 7 servers.
I am getting the error below and have attached my config files

Let's dissect these two lines in the error

SCServer

the first line states that the template SCServer can not be found. This template is defined to be used in many of the host definitions you have in SCServers-RTP.cfg.txt but neither of the files you posted contain a definition for SCServer and it appears that nagios cannot find it as well.

I would suspect that that template would contain the max_check_attempts that is missing from all of your definitions.

It should looks something like this and can go in any file that is included in the config

Code: Select all

define service {
    name                            SCServer
    max_check_attempts              5
    check_interval                  10
    retry_interval                  2
    check_period                    24x7
    check_freshness                 0
    notification_interval           60
    notification_period             24x7
    notifications_enabled           1
    register                        0
}

Did you add the definition example above to a file that is included in the configs?

I have added to the SCServers.cfg file what was to be added but nothing changed.

You need a host template defined called 'SCServer'.

The default config has a templates.cfg file that you can find an example template to copy and turn into the missing template.
